Accession and Pathway Details

Accession Name	Accession No.	Accession Type	Pathway Link
AMPAR_CaMKII_ strong_coupling	64	Network	Shared_Object_AMPAR_CaMKII_strong_coupling,  CaMKII,  CaM,   PP1,  AMPAR_memb,  PP2B,   PKA,  AC,  PP1_PSD,   AMPAR
This is a model of tight coupling between the AMPAR trafficking bistability, and the CaMKII autophosphorylation bistability. In this model, the CaMKII activity is self sustaining only when AMPAR is turned on. Further, CaMKII turns on when AMPAR is turned on.

CaNAB-Ca4 acting as a Substrate in a reaction in  AMPAR_CaMKII_strong_coupling Network

Kd is calculated only for second order reactions, like nA+nB <->nC or nA<->nC+nD, where n is number and A,B,C,D are molecules, where as for first order reactions Keq is calculated. Kd for higher order reaction are not consider.

This process is probably much more complicated and involves CaM. However, as I can't find detailed info I am bundling this into a single step. Based on Steemer and Klee pg 6863, the Kact is 0.5 uM. kf/kb = 1/(0.5 * 6e5)^2 = 1.11e-11
